    Multi-Node Tree Picker if it is empty..

     

    hey guys

    I have a Multi-Node Tree Picker and it is empty, this gives an error.

        foreach (var x in item.refKursus) 
       {
         var n = @Model.NodeById(@x.InnerText);
         var nSta =@n.kursusStartDato.ToString("dd");
         var nEnd = @n.slutDato.ToString("dd. MMMM yyyy");
         <em class="date">@nSta<text>.</text> - @nEnd</em>
           }

     

    Error loading Razor Script BlockHolding.cshtml
    Input string was not in a correct format.

     


    What can solve this? I will try if else but null and "" gives me  an error.

    Error loading Razor Script BlockHolding.cshtml
    Operator '!=' cannot be applied to operands of type 'umbraco.MacroEngines.DynamicXml' and 'string

    Many thanks

    /Johan

     @if (@Model.HasProperty("mntpicker") && @Model.GetProperty("mntpicker").Value != String.Empty){
            <ul>
             @foreach (XElement elem in Model.mntpicker.BaseElement.Elements("nodeId"))
             {
               var theNodeInSideThePicker = @Model.NodeById(elem.Value);         
               <li>
                 @theNodeInSideThePicker.Name
               </li>
             }
            </ul>
    }
    1. Check first if the property exists and has a value
    2. Run over the xml inside the propertyvalue
    3. Get the nodes inside the picker by those ID's
    4. Do your stuff

    Thank you Bert, it was just what was needed!

    my code is now:

    @if (@item.HasProperty("refKursus") && @item.GetProperty("refKursus").Value != String.Empty)
    {

      foreach (var x in item.refKursus) 
      {
      
          var n = @Model.NodeById(@x.InnerText);
          var nSta =@n.kursusStartDato.ToString("dd");
          var nEnd = @n.slutDato.ToString("dd. MMMM yyyy");
          <em class="date">@nSta<text>.</text> - @nEnd</em>
      }
    }

    Her's my 5 cents 

    @if (@item.HasValue("refKursus"))
{
    // do your stuff
}

    Hope it will help some one (c:
